A recent study observed sleeping participants' pupils during sleep, using a new method that could have implications for ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A ...

ETH Zurich researchers found that pupil size changes during sleep, indicating shifts in brain activity. This could help ...

The pupil responds to light, which is essential for our vision and how we see our surroundings. Three known mechanisms change ...

Cornell University researchers have found that the pupil is key to understanding how, and when, the brain forms strong, long-lasting memories. By studying mice equipped with brain electrodes and ...

For this reason, pupil size is often used in psychology and neuroscience research as a measure of mental effort and attention. For many decades, these three kinds of pupil response were the only ...

Researchers from Cornell University informed that pupil is key to understanding how, and when the brain forms strong memories that have a long recall value. The researchers studied mice with brain ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A ...

Attitude and Pupil Size Dilation and constriction of the pupils reflect not only changes in light intensity but also ongoing mental activity. The response is a measure of interest, emotion ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during ...
